Quantifying interstellar extinction at high Galactic latitudes

Published in MNRAS, 2024

A detailed map of the distribution of dust at high Galactic latitudes is essential for future cosmic microwave background polarization experiments because the dust, while diffuse, remains a significant foreground in these regions. We develop a Bayesian model to identify a region of the Hertzsprung–Russell (HR) diagram suited to constrain the single-star extinction accurately at high Galactic latitudes.
